Description
Technical field
The utility model relates to the press key sealing structures of motorcycle instrument, especially motorcycle instrument.
Background technique
Motorcycle instrument is usually provided with the key that controllable instrument shows content, and water or dust enter instrument in order to prevent
It needs that sealing structure is arranged inside table, at key, referring to Fig.1, in the prior art, press key sealing structure includes button cap 5 ', modeling
Expect that pressing plate 6 ' and key 3 ', button cap 5 ' are pressed abd fixed in the counterbore of surface of shell by plastic presser plate 6 ', key 3 ' is located at
5 ' lower section of button cap, plastic presser plate 6 ' are welded on instrument housing 1 ' by ultrasonic equipment；Above-mentioned sealing structure needs to put into
Expensive ultrasonic equipment and special operation board, and increase circulation process, so that complex process, and to assembly essence
Degree has higher requirements, and substantially increases the cost of production；In addition, after using ultrasonic bonding, be not easy to key maintenance and
Replacement.
Summary of the invention
For overcome the deficiencies in the prior art, the meter key that the utility model provides a kind of simple process, is easily assembled
Sealing structure.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of key of motorcycle instrument seals knot
Structure, including instrument upper housing and lower case, the key base of lower case are equipped with the key that control instrument shows content, key housing
Equipped with button cap, upper housing is equipped with key channel and is pierced by for the button cap, the button cap have the brim of a hat be resisted against it is described by
Key channel bottom wall, the key is set with pressing plate outside and the pressing plate is resisted against on the key base, and the pressing plate has separate
The boss that key base direction is extended protrudes into the button cap, and the side wall of the button cap is pressed at the key channel
Realize the installation fixation and the sealing in the key channel of the button cap.
There is the pressing plate step surface to be resisted against the bottom wall of the brim of a hat and the brim of a hat is pressed on to the bottom in the key channel
On wall.
The boss includes the first compressed part of lower part and second compressed part on top, the ruler of the first compressed part width direction
It is very little to be greater than the second compressed part.
The key channel has extended downwardly conduit wall, and the brim of a hat of the button cap has groove, the conduit wall sandwiched
In in the groove.
It extends downwardly out pillar at the top of the button cap and terminates in keys upwards.
The beneficial effects of the utility model are: 1, be not required to the high ultrasonic equipment of input price and special operation board
And the process that individually circulates, reduce production cost；2, the peace of button cap is realized to button cap sidewall extrusion by pressing plate boss
The sealing of dress and key channel, simple process is easy to assembly, is also convenient for later period dismounting maintenance；3, low to assembly precision requirement, i.e.,
Make other components occur laterally to misplace with vertical assembly and also can guarantee sealing, reduces processing request.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the partial sectional view of the prior art；
Fig. 2 is the structural schematic diagram of the utility model；
Fig. 3 is the fractionation structural representation of the utility model；
Fig. 4 is the A-A partial sectional view of Fig. 2.
Specific embodiment
Referring to Figure 2 to Figure 4, a kind of press key sealing structure of motorcycle instrument, including instrument upper housing 1 and lower case 2, under
The key base 31 of shell 2 is equipped with the key 3 that control instrument shows content, is arranged with button cap 5 outside key 3, upper housing 1 is equipped with
Key channel 4 is pierced by for the button cap 5, and there is the button cap 5 the brim of a hat 51 to be resisted against 4 bottom wall of key channel, described
Pressing plate 6 is set with outside key 3 and the pressing plate 6 is resisted against on the key base 31, and the pressing plate 6 has far from key base direction
The boss 61 extended protrudes into the button cap 5, and the side wall of the button cap 5 is pressed at the key channel 4 and is realized
The installation fixation and the sealing in the key channel 4 of the button cap 5.
When installation, first the suit of pressing plate 6 is worn and is connect on key 3, then covers button cap 5, finally by upper housing 1, lower case 2
Gai He realizes the sealing in key channel 4, together at this point, the side wall of button cap 5 is pressed on 4 inner wall of key channel by pressing plate boss 61
When also by button cap 5 install fix, simple process is easy to assembly, and be also convenient for the later period dismounting maintenance；Meanwhile above structure pair
Assembly precision requirement is low, can guarantee sealing offset dislocation laterally or vertically occurs for other component；On the other hand, it is not required to
The ultrasonic equipment and special operation board that come into operation again with high costs and the process that individually circulates, reduction are produced into
This.
As a preferred embodiment of the present invention, there is step surface 62 to be resisted against the bottom wall of the brim of a hat 51 and incite somebody to action for the pressing plate 6
The brim of a hat 51 is pressed on the bottom wall in the key channel 4, by the boss 61 of pressing plate 6 and step surface 62 by button cap 5
Side wall and the brim of a hat 51 are pressed on the side wall and bottom wall in key channel 4, make button cap 5 simultaneously to key channel 4 carry out it is axial and
Better seal effect is realized in radial dual-seal.
Preferably, the second compressed part 612 of first compressed part 611 and top of the pressing plate boss 61 including lower part,
The size of first compressed part, 611 width direction is greater than the second compressed part 612；When assembly, the second compressed part 612 facilitates guiding, just
Button cap 5 is protruded into pressing plate boss 61, is preferably bonded on 5 inner wall of button cap, the first compressed part 611 that lower part broadens can be with
The side wall of button cap 5 is compressed well, so that sealing is more reliable.
Preferably, the key channel 4 has extended downwardly conduit wall 41, and the brim of a hat 51 of the button cap 5 has groove 52,
The conduit wall 4 is located in the groove 52, so that the brim of a hat 51 of button cap 5 is tightly hooked below key channel 4, is avoided
Button cap 5 is pulled out, and the conduit wall 41 extended downwardly can be such that 5 side wall of button cap is become much larger by the area that pressing plate 6 presses, and reach
To better seal effect.
In order to enable users to more clearly distinguish the position of key, button cap 5 is exposed and protrudes 1 surface of upper housing, at this time
If the roof of button cap 5 apart from key 3 farther out if be not easy to touch key 3, for this purpose, at the top of button cap 5 to downward
Pillar 53 is stretched out, to fill up the distance between 5 roof of button cap and key 3 gap, when user is in pressing keys cap 5, energy
Key 3 is more easily touched, to realize response.
